3 Claims.

The present invention relates to improvements in shoe construction, and is more particularly adapted for use in the manufacture of turn shoes.

In turn shoes as usually constructed, there may 5 be a leather shank piece which is put in the shoe after it has been turned right side out, and which is provided at its lower base with a metal stiffener. The shank-piece may consist of a heel portion and a shank portion. With the shank-piece and the sole prepared as heretofore, it was substantially impossible, notwithstanding the great pressure exerted in pressing the shank-piece and the sole together, to make them fit close together at the sides of the shank of the finished shoe so as to allow no gap to appear between the sole and the shank-piece.

In shoes in which the material of the shoe upper extends along the entire edge of the sole, such gap would not be particularly noticeable,

and this would be especially true of the heel portion of the shoe where a counter is used. However, in the case of an openshank and open-heel shoe, this gap would be very noticeable.

It is therefore an important object of the pres- 5 ent invention to find a way to obviate such difiiculties.

According to the usual practice of making turn shoes, each sole is provided along its continuous edge and on its lower face with a socalled In order to obtain a close fit between the edge of the sole and the shank of an openshank shoe, the shank piece may, according to the present invention, be provided with a bead or ri-dge at its lower face and along both sides of 5 the shank so that, when the shank-piece and the sole are pressed together and secured, their edges will be close together and will remain in that close-fitting condition for a long period. In fact, when the beaded portion of this shank-piece and 40 the shank portion of the sole are pressed together under heavy pressure, there is produced a locking together of the shank and the sole so that the two cooperate in producing a'strong arch support. It should be understood that the 45 marginal bead or ridge may be formed by recessing the lower face of the shank-piece in any suitable manner.

In the case of a shoe having an open heel as well as an open shank, the shank-piece may be 50 provided with a marginal bead or ridge extending around the heel portion of the shank-piece, and preferably connecting the beads at the side edges of the shank portion. This formation of the shank-piece makes it possible to avoid gaps be- 55 tween the edges of the sole and the shank-piece at the heel as Well as at the shank of an openshank and open-heel shoe.

Other objects, features and advantages of the invention will appear upon consideration of the following description and of the drawing, in which Fig. 1 is a perspective view illustrating more particularly the lower or sole-engaging side of one form of shank-piece embodying the present invention;

Fig. 2 is a fragmentary perspective view illustrating the appearance of the upper side of the sole for a turn shoe;

Fig. 3 is a view similar to Fig. 1, but for a modifled form of shank-piece; 15

Fig. 4 is a fragmentary side view of an openshank shoe constructed with a shank-piece as illustrated in Fig. 1;

Fig. 5 is a fragmentary side view of an openshank and open-heel shoe with a shank-piece as 20 shown in Fig. 3; and

Fig. 6 is a section on line 66 of Fig. 4.

Referring to the drawing, Fig. 1 illustrates a shank-piece ll) of suitable material, such as leather, and comprising a heel portion II and a 5 shank portion l2, having on its sole-engaging face marginal beads l3, which may be formed by providing recesses in the shank-piece. The shank-piece is preferably provided also on its sole-engaging face with a metal reinforcing mem- 0 her I4 firmly secured to the shank-piece. The shank-piece l0 having marginal beads l3 at its shank-portion is particularly adapted for use in makin an open-shank shoe l5 such as is illustrated in Fig. 4.

This shoe I5 has a sole l6 which, as illustrated in Fig. 2, has a feather I! projecting from the edge of the sole proper at its lower face and extending completely around the periphery of the sole. The sole [6 is further provided at its upper 40 side with a channel flap l8 extending around the periphery of the sole in the part which projects above the feather l7. When the shank portions of the shank piece l0 and the sole I6 are pressed together under heavy pressure, the beads 13 on shank-piece H! are forced down at the outside of the channel fiap l8 of the sole so that there will be no gap above the feather l1, and shank-piece l0 and sole [6 will be locked together at their edges. In this connection it should be noted that the recesses at the inner sides of the beads l3 of the shank piece I0 should be just deep enough to receive the channel flap on the sole IS.

The shoe I5. is illustrated in Fig. 4 as having a vamp l9 attached to the sole to the front of the open-shank portion, a heel 20 and section 2| of an upper above the heel and provided preferably with a counter therein, the shoe being adjustably secured on a foot by means including a strap 22 extending rearwardly from vamp I9 for attachment to a strap 23 extending from the upper portion 2| by means such as a buckle 24. It should be understood that the feather i1 is preferably brought down to a thin edge so as not to be too conspicuous.

In the open-shank shoe illustrated in Fig. 5, there is no heel portion of the upper, and the shoe is therefore not only an open-shank shoe but also an open-heel shoe. With this form of shoe it is important to avoid a gap between the heel portion of the sole and the heel portion of the shank piece. In this form of shoe, use is made of a shank piece 25 comprising a heel. portion 26 and a shank portion 21 and having a marginal bead 28 around said heel portion 26 and along'both sides of the shank portion (Fig. 3). It will be evident that the use of the shank-piece 25 tends to prevent all gaps between the sole and the shank-piece not only along the sides of the shank but also around the heel of an open-shank and open-heel shoe.

It should be understood that various changes may be made and that certain features may be used without others without departing from the true scope and spirit of the invention;

Having thus described my invention, I claim: 1. An open-shank shoe comprising a sole having at its shank portion and at the lower face of between the feather and the bead in the shank.

2. A shoe with an open shank and an open heel comprising a sole having at its margin and lower side a continuous feather, and a shank-piece engaging the upper side of the sole and having at its lower side a marginal bead extending around the heel portion and throughout the sides of the shank portion and engaging closely the feather so that there is substantially no gap between the edges of' the sole and the shank-piece around the heel and the shank portion of the shoe.

3. A shank-piece for an open-shank shoe, havingthroughout each side of its shank portion a bead to fit closely over the outer edge of a channel flap of a sole having a marginal feather, the bead being formed by providing a recess just inside the bead and just deep enough to receive the channel flap on the sole, so that the outer edges of the sole and the shank-piece may fit closely together along the shank portion of the shoe.
